Laterals separated by slightly more than twice the diameter of ALE. 
Clypeus quite porrect; with one erect spine beneath interval separat- 
ing AME and two erect spines on each side near ventral border; height 
nearly equal to eight times the diameter of AME. Mouth parts es- 
sentially typical of females of the genus. Legs: 1243 in order of 
length; spines are numerous and, in general, typical of females of 
the genus ; trichobothria essentially as in male, also observed on palpal 
tibiae. Abdomen: very spiny and irregular along dorsal region (prob- 
ably associated with shrinkage following deposition of eggs) ; with 
a well developed posterodorsal tubercle projecting upward at an 
angle ; somewhat the widest in front of base of posterodorsal tubercle. 
Epigynum : essential features shown in Figure 6 ; some variations 
noted among paratypes. Color in alcohol : essentially as decribed for 
male but all colors are more vivid than in that sex; first two pairs of 
tarsi and metatarsi not reddish as in male but irregularly yellowish 
brown. 
Type locality. Male holotype and female paratype taken on north- 
east slope of Long Mt., St. Andrew Parish, Jamaica, W. I., October 
26th, 1957. Numerous paratypes of both sexes were taken with the 
holotype and also in St. Catherine Parish, Hanover Parish, and on 
other parts of St. Andrew Parish in 1954, 1957 and 1963. 
Tmarus insuetus sp. nov.

The name of the species is a Latin adjective suggested by the 
unusual type of male palp. 
Male holotype. Total length 4.03 mm. Carapace 1.5 mm long; 
1.5 mm wide; .63 mm tall; surface very finely granulate; with numer- 
ous long, slender spines; posterior declivity gently arched, not steeply 
slanted. Eyes : ocular tubercles less prominent than usual in the genus 
but otherwise typical of the genus; viewed from above, posterior row 
rather strongly recurved, anterior row moderately so; viewed 
from in front anterior row slightly recurved, measured by 
centers. Central ocular quadrangle wider behind than in front 
in ratio of 1 1 : 8; longer than wide behind in ratio of 13 : 11. 
Posterior row occupies about 6/7 of width of carapace at that level. 
Ratio of eyes AME : ALE : PME : PLE = 4:10:5:9. AME 
separated from one another by twice their diameter, from ALE by 
2.75 times their diameter. PME separated from one another by 2.6 
times their diameter, from PLE by nearly five times their diameter. 
Laterals separated from one another by about 2.2 times the diameter
